Do self-test systems still require annual contractual maintenance? Fire Service enforcement officers always ask for proof of contractual maintenance and testing of emergency light systems

That would depend on the installation type. Where the lighting is part of a central testing system or is an addressable system powered and tested from a central source then there are technical elements that require external maintenance one or two times a year.

If they are just a large quantity of self contained self testing units then as they carry out the monthly and annual tests in theory you don't need anymore than the monthly walkaround to check the visual indicators and for any damage with the wiring side checked in the 5 year EICR.

The law only requires "A suitable system of maintenance". Keep a log of monthly checks and manufacturers data showing these are self testing and the system of maintenance doesn't require the traditional service visits and you are legal regardless of what a fire officer, used to standard fittings, wants.

Of course of the manufacturer's data requires a service (such as with a central system) then that's what you have to do.

I have a similar question. Our fire risk assessment says we need to install emergency lighting in accordance with BS 5266 Part 1. A general electrician has recently been contracted by the freehold management company to install emergency lighting which is self testing. The electrician advised that no record keeping is required or any testing other than replacing each device when the led shows red. I am wondering if that is correct or should I follow up on anything.

Thank you for your help

You would still preferably need a formal monthly check, recorded to prove it's done, just to check the LED status & identify failed units, but not much else.
